In case you’re wondering, none of the children’s due dates were Jan. 12 either. The couple, who has been together for seven years living in the U.K., said their eldest son was born late, the twin girls were delivered early in an emergency Cesarean section and their newest addition, a boy, just happened to be born on Sunday, a bit later than his due date.

“I’m still trying to work out if it would be easier to have birthdays spread throughout the year or all on the same day,” the 24-year-old father said, according to the newspaper. “It doesn’t matter though, we plan to make every birthday a real family event where birthdays get celebrated individually and together.”

It was also pointed out that Jan. 12, 2030, will be a big year for all the children. The eldest will turn 21, the twins will turn 18 and the couple’s now-newborn son will be 16 years old.
